越来越多的研究表明,早期青光眼患者在视力下降、视野缺损之前,就已有中心视功能受损。近年来,通过对早期青光眼的色彩分辨力,视觉对比敏感度、视诱发电位以及黄斑光阈值的检测和研究,均证实青光眼早期在中心视力下降和视野改变前即存在黄斑功能的损害。为了进一步探讨早期青光眼黄斑光阈值改变的特征,了解正常人黄斑光敏感性的特点,我们对正常人不同年龄组的黄斑光阈值进行了检测。
More and more studies have shown that patients with early glaucoma have had impaired central visual function before their eyesight deteriorates and their visual field is deficient. In recent years, through the early glaucoma color resolution, visual contrast sensitivity, visual evoked potential and macular threshold detection and research have confirmed early glaucoma in the central vision decreased and visual field before there is a change in macular damage. In order to further investigate the characteristics of macular light threshold changes in early glaucoma and to understand the characteristics of macular light sensitivity in normal subjects, we examined the macular light threshold in different age groups of normal subjects.
